Flexible, open source, and powered by defenders. Zeek has a long history in the open source and digital security worlds. Vern Paxson began developing the project in the 1990s under the name “Bro” as a means to understand what was happening on his university and national laboratory networks. Vern and the project’s leadership team renamed Bro to Zeek in late 2018 to celebrate its expansion and continued development. Zeek is not an active security device, like a firewall or intrusion prevention system. Rather, Zeek sits on a “sensor,” a hardware, software, virtual, or cloud platform that quietly and unobtrusively observes network traffic. Zeek interprets what it sees and creates compact, high-fidelity transaction logs, file content, and fully customized output, suitable for manual review on disk or in a more analyst-friendly tool like a security and information event management (SIEM) system.

Pros & Cons from Real Users Pros Splunk is top of the line for logging. But that means paying a lot every month, and keeping a lot of data, so make sure you actually need detailed logging. If you do, Splunk has a lot of built in functions to analyze your logging data and help your business be more insightful. Customizable dashboards. Can consume multiple log sources. Extensive and deep search feature. Search Queries can be converted to apps. Alert system based on log data. Cons If you only need some of the metrics and not all the logs, getting Splunk means you're wasting money and overengineering your analytics process. You can use an open source metrics system like Prometheus instead if that's what you need. It's also super easy to accidentally get false alerts on Splunk, and that will not make your oncall engineers happy. Steep learning curve. Search can be slow for huge logs. Expensive.
